For example, if a federal agency is collecting the DNA sample from an arrestee, the “Federal Arresting Agency” box should be selected. However, if the same federal agency is collecting the DNA sample from a detainee, the “Federal Detainee Agency” box should be selected. It is essential that this section is filled out completely and correctly. Additional questions on how to properly complete this section may be directed to the FDDU at (703) 632-7529.

Buccal Collection Procedure

Buccal Collection Procedure: Buccal Collection Procedure

Each kit will have a detailed instruction sheet for how to obtain a buccal sample.

  • Open the FTA Card end of the protective sleeve and partially slide out the device.

Buccal Collection Procedure: Opening Device

  • Leave the foam applicator in the protective sleeve.
  • Turn over the device and slide the FTA card out of the device.

Buccal Collection Procedure: Recording Offender Name

  • Record the offender name, collection date, and collector name on the FTA card. Samples without this information will not be accepted.


  • The information recorded on the FD-936 must be identical to the information captured on the DNA collection card. Failure to do so will result in the rejection of the DNA sample by FDDU.
  • Slide the FTA card back into the collection device.
  • Remove the device completely from the sleeve.
  • Hold the plastic stem and angle it slightly. This is the collection position.
  • Place the foam applicator into the mouth.

Buccal Collection Procedure: Foam Applicator in Mouth

  • Soak up as much saliva as possible by running the applicator along the gum-line, at the fold line in the cheek, and under the tongue.
  • Then, swab the inside of the cheeks for 15 seconds.
  • Remove the plastic protective film from the FTA card holder.

Buccal Collection Procedure: Remove the Film

  • Fold device at the hinge joint.

Buccal Collection Procedure: Closing Buccal Device

  • Press the foam applicator onto the FTA card and snap down two notches to the lowest position on the stem snap located on the handle. Ensure that there is contact between the foam head and the FTA card.

Buccal Collection Procedure: Closing Buccal Device

  • Leave the foam applicator in contact with the FTA card for at least 10 seconds.
  • Release the foam applicator from under the foam head snap by bending back on the handle of the device.
  • Fold the stem again and snap into the top position on the stem snap. This ensures the foam applicator is not touching the FTA card.

Buccal Collection Procedure: Closing Buccal Device 2

  • Allow the FTA card to dry for five minutes.

Buccal Collection Procedure: Buccal Drying

  • Package in the supplied buccal collector envelope.

Buccal Collection Procedure: Packaging

  • The envelope should be closed using the self-adhesive strip, and if applicable, tape. Do not moisten envelope with saliva to close.
  • Repeat buccal collection with the second buccal collection device.


  • The FD-936 form and the two pouches containing the buccal collection devices should be placed into the white return envelope.


  • Remove the adhesive backing and seal the envelope.




  • Kits should be mailed within 24 hours to the FBI Laboratory using the United States Postal Service.
  • Postage is not necessary.

Kit Rejections

  • Kits will be rejected for the following reasons:
    • The name on the FD-936 form does not match the name on the FTA card.
    • No name on the FD-936 form or FTA card.
    • No fingerprints or illegible fingerprints on the FD-936 form.
    • Damaged evidence seal.
